UE5.4 shadow flickering/jitter on meshes at distance and in profile view

Development Rendering

Shadow flickering/jitter appears on meshes when the camera is at medium/far distance or viewing objects from a profile angle in UE5.4. The issue is visible even with Lumen disabled. The issue only occurs on rough surfaces, on any rough mesh or meshes with small gaps. Any ideas? ty!

This is aliasing, specifically in the form of a moire pattern. You can look this up, it’s a ubiquitous problem in realtime computer graphics. It is typically a problem specific to geometry, because when the detail is in a texture the mipmaps are used and they’re pre-filtered, so if you can make the surface pattern a texture rather than geometry, it should resolve the problem.

Otherwise, you can read through the TSR documentation, it has an entire section specifically dedicated to this issue: Temporal Super Resolution in Unreal Engine | Unreal Engine 5.7 Documentation | Epic Developer Community

Thanks for replying, I’m still trying to figure it out.
